Storyline

Rival Lebanese politicians failed to reach agreement when they returned to the negotiating table on Saturday, a day after the government received a draft document setting up an international tribunal to try suspects in the 2005 assassination of former Prime Minister Rafik Hariri.

Politicians emerged from the meeting, with some saying the talks failed to achieve a breakthrough.

In a sign of worsening tensions, Christian leader Michel Aoun said the talks had failed to produce an agreement and that no date for another round of talks was set.

Christian politician Samir Geagea acknowledged the talks had failed to reach any agreement but suggested the talks would resume at a later stage.

He said the meeting was stopped partly because House Speaker Nabih Berri was scheduled to leave to travel to Iran.

"We have not achieved any progress and Speaker of the House, Berri is travelling. I do not know who is trying to spread fear and panic for what is going to happen on Monday. Nothing is going to happen and we have not reached any agreement."

The handover of the draft document setting up an international tribunal to the Lebanese government on Friday figured high on the agenda of Saturday's meeting, the fourth this week aimed at solving differences between Lebanon's bickering politicians.

The stakes of the talks are high: the Iranian and Syrian-backed Hezbollah guerrilla group threatened protests that could bring down the government if its share in Cabinet portfolios is not increased.

Lebanese media reports have suggested the anti-Syrian parliamentary majority led by the late Hariri's son, Saad, would agree to give Hezbollah and its allies a larger share of the Cabinet and effective veto power over key decisions if the group and allied pro-Syrian factions endorse the draft for the tribunal.

But Hariri's allies denied that such a deal was on the table.

The anti-Syrian majority has accepted the principle of forming a national unity government but refuses to give Hezbollah and its allies the one-third of Cabinet posts that is effectively equivalent to veto power because Cabinet decisions require approval by two-thirds of the ministers.

They also want to discuss the fate of President Emile Lahoud, a staunch pro-Syrian who has rejected pro-government demands to step down.
